T0 ALL WHOM IT MAY CONGERN:

Be it `known that I, CHARLES HAMILTON HAsKINs, of St. Louis, in theState of Missouri, have invented a i i new anduseful Improvement on` thepre sent Plan oi' Ventilating Passenger-Cars and other publicconveyances and I do hereby declare that the followirigis `a full,clear, and exact description of the construction and operutiorof thesame, reference being hadto the annexed drawings, making a part ofYthis.speciieatiomin which- Figure 1 is a perspective view of the.whole-machine. Y Figure 2 is `a longitudinal section showing theinternal arrangement and construction of parts. Figure 3 is a plan ofthe upper part or windmill.

Figure 4 is "a plan of the lower part showing eaves-trough.

` In each of these, a represents the windmill;` the eavesftr'ough; e theinlet for Ventilating the air; ai the outlet-pipe for puriied airentering the car; e the partition to prevent the -water from beingthrown out of the box; fthe worm or screw-pipe w the water, Sie.

The nature of my invention consists of a. water-tightbox, of anymaterial, divided horizontally into two compartments, the lower `tocontain water Vfor the purpose of cleaning the air beforeit isintroduced into the car or conveyance; the upper compartment containinga windmill', to which is attached a screw-pipeor worm,

extending down into the water below, by whose rapid motion the water iscarried up and emptied upon aneavesl I trough, b, surrounding the upperpart of the lower box or compartment. This eaves-trough-being perforatedwith holes, permits the water to fall again in drops, so that the airpassing throughthe inlet c and the' outlet d,

is washed and divested of all dust and smoke, and permitted to enter thecars perfectly pure 'and fresh. The

lower compartment is furnished also with projecting riiiies on thebottom and sides, to check and prevent any which the water is raised. p

-But what I do claim as my invention, `and desire to secure by LettersPatent, is

1. The use of an eaves-trough or its equivalent, to hold the water' whenraised, allowing it to fall in sheets i l or drops in quantity asrequired, as and for the purposes set forth. l i i 2. 'I claim thecombination of the windmill, the worm or screw-pipe, and thecaves-trough, or their. equivalents, sbstantially as described for thepurpose herein set forth,
